A
Current drop
B
Potential drop
C
No current drop
D
No potential drop
Answer
Potential drop
Explanation
Solution

This increased total current flowing through the internal resistance of the electric mains (or house wiring) causes a significant potential drop across it. Consequently, the voltage available to other parallel appliances like bulbs decreases, leading to their dimming.
